the numbers above I would say are the ones most widely used
Unless the numbers are based on a rational statistical analysis with sensible error bounds on their subsequent use, they are not a great deal of use so far as validity is concerned.
Australia uses data originally developed by CASA's then John Klingberg some years ago based on medical statistical data for the then Australian population. John's original report makes for interesting reading - the final operational output is at
CAAP 235-1(1)
It follows that any study periodically needs to be revisited to maintain a semblance of policy validity.
